BACKGROUND 1. Field

One or more embodiments relate to a bio-signal measuring device and a bio-signal measuring method.

2. Description of Related Art

In order to maintain human life, there is a need for a process of enabling blood released by the heartbeat to flow along the arteries to all parts of the body without clogging and returning blood through the veins back to the heart. Accordingly, oxygen and nutrients may be supplied to the body's tissues, and consumed wastes may be removed through the metabolism.

However, when the human heart is in a poor condition, blood may not be properly delivered to particular parts of the body or a blood clot or embolism may occur in the blood. As a result, blood may become cloudy, and the cloudy blood may block capillaries, in particular tissues of the body, and cause tissue necrosis, and thus, the human life may be in danger. Therefore, in addition to clinical examinations, imaging tests and the like have been used to examine whether or not the heart is abnormal. Also, as an early diagnosis method, a method of determining whether or not a patient has an abnormality in the heart by measuring an electrocardiogram and displaying the measured electrocardiogram signal on a graph has also been widely used.

In other words, an electrocardiogram refers to recording of a potential change in the surface of the body that causes the mechanical activity of the heartbeat, such as contraction or expansion of the heart muscle. The electrocardiogram is a non-invasive test that is simple to measure, is easily reproduced, is easily repetitively recorded, and is inexpensive to test. The electrocardiogram has been used helpfully to diagnose arrhythmia and coronary artery disease (cardiac artery disease) and to monitor the progress of cardiac patients.

In general, the electrocardiogram is measured by attaching sensors for measuring electrocardiogram signals on the upper left and right and lower left and right of the chest and by using potential differences according to the location of the sensor.

However, the present disclosure is not limited to the embodiments described below, and may be embodied in various modes.

Hereinafter, one or more embodiments will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view for explaining a bio-signal data processing system according to one or more embodiments.

As shown in FIG. 1, in the bio-signal data processing system, bio-signal measuring devices 301, 302, 303, and 304 (hereinafter referred to as a bio-signal measuring device 300) store bio-signal data by measuring bio-signal data and transmitting the bio-signal data to a portable electronic device 100.

The bio-signal measuring device 300 may be a device for measuring a bio-signal through the body of a user and measure blood pressure, blood sugar, heartrate, oxygen saturation level, sleep time, depression diagnosis, chemical analysis, weight, exercise load, an electrocardiogram, and the like.

The portable electronic device 100 stores, in a memory, the bio-signal data received from the bio-signal measuring device 300. The portable electronic device 100 is connected to a communication port of electronic devices 201 and 202 (hereinafter referred to as an electronic device 200) to perform various operations through the electronic device 200. For example, the portable electronic device 100 may enable the bio-signal data to be output through the electronic device 200. The portable electronic device 100 may transmit the bio-signal data to a preset electronic mail through the electronic device 200. The portable electronic device 100 controls processing, such as preset output, data copy, and data movement, to be performed rather than stores the bio-signal data in the electronic device 200.

The electronic device 200 may include one or more processors and a communication interface for communicating with external devices and may include an output unit with a user interface. As shown in FIG. 1, the electronic device 200 may be a desktop computer 201 or a smartphone 202 but is not limited thereto. The electronic device 200 may be implemented as a smartphone, a table personal computer (PC), a mobile phone, a video phone, an e-book reader, a desktop PC, a laptop PC, a netbook computer, a workstation, a server, a personal digital assistant (PDA), a portable multimedia player (PMP), an MP3 player, a mobile medical device, a camera, a wearable device, or the like.

In the bio-signal data processing system, the bio-signal measuring device 300 refers to a device for measuring bio-signal data. For example, the bio-signal measuring device 300 may be a device which is mounted on an object noninvasively or invasively to detect an electrocardiogram. Here, the object may be a human, an animal, or part of the body of a human or animal such as the chest but is not limited thereto. The object may include all types of objects from which electrocardiograms may be detected or measured. Also, an electrocardiogram is a graph that records changes in a potential on the surface of the body causing the mechanical activity of the heartbeat such as contraction/expansion of the myocardium. Here, the meaning “detect an electrocardiogram” may mean the same as “detect a potential” on the surface of the body.

As shown in FIG. 1, the bio-signal measuring device 300 may be implemented in the form of a wristwatch, glasses, and the like to measure a bio-signal.

The bio-signal measuring device 300 may communicate with the portable electronic device 100 by including a near field communication module. Here, the near field communication module refers to a module for performing communication with an external device located at a short distance, according to near field communication methods such as Bluetooth, radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), and ZigBee. The bio-signal measuring device 300 may further include a band-type mounting part. The mounting part may be made of a flexible material that may be deformed to fit a curved surface of the surface of the body, for example, an elastic (i.e., flexible) fabric. The mounting part may be provided as a patch-type or a wearable type. As long as the bio-signal measuring device 300 is worn through the mounting part, the bio-signal measuring device 300 may detect a potential generated on the surface of the body by contacting the surface of the body of the object obj.

FIGS. 2 and 3 are block diagrams of portable electronic devices 100 and 100 a according to one or more embodiments.

As shown in FIG. 2, the portable electronic device 100 may include a processor 110, a Bluetooth module 120, a communication interface 130, an internal battery 140, and a memory 150.

The processor 110 stores, in the memory 150, bio-signal data received from the bio-signal measuring device 300.

The processor 110 detects communication connection to the electronic device 200 through the communication interface 130. The processor 110 may determine whether or not connection to the electronic device 200 is maintained by authenticating a certificate of the electronic device 200 or a password input from the electronic device 200. For example, the processor 110 accesses the certificate stored in the electronic device 200 to determine whether or not a certificate is approved and maintains connection to the electronic device 200 storing the approved certificate. The processor 110 may determine whether or not the electronic device 200 is approved by transmitting, to the electronic device 200, a control signal for providing a password input screen and receiving a password input through the password input screen.

The processor 110 may transmit, to the electronic device 200 that is connected, bio-signal data or an output control signal of the bio-signal data.

The processor 110 stores, in the memory 150, the bio-signal data received through the Bluetooth module 120. The portable electronic device 100 may further include a state for notifying an operation of the Bluetooth module 120 or the like. The Bluetooth module 120 may receive and transmit data by using a frequency band of about 2400 MHZ to about 2483.5 MHZ. The Bluetooth module 120 may receive and transmit data while hopping one or more frequencies from among frequencies within a frequency band. For example, the Bluetooth module 120 may operate by receiving first data at a first frequency in one communication session and then changing the first frequency to a second frequency to receive second data.

The communication interface 130 may transmit the bio-signal data and the control signal to the electronic device 200. The processor 110 stores, in the memory 150, data received through the Bluetooth module 120 and transmits in real time, to the electronic device 200, data received through the communication interface 130. FIG. 1 illustrates that the communication interface 130 is a wired USB, but the communication interface 130 may be a wireless method.

The signal detector 310 may detect a bio-signal such as blood pressure, blood sugar, heartrate, oxygen saturation level, sleep time, depression diagnosis, chemical analysis, weight, the amount of exercise, or an electrocardiogram. The signal detector 310 outputs an electrocardiogram analog signal by detecting an electrical signal from the heart of an object. The signal converter 320 may convert the bio-signal into a digital signal. The signal converter 320 may convert the electrocardiogram analog signal into an electrocardiogram digital signal.

The processor 330 may be implemented to operate in several operation modes in association with processing of the electrocardiogram digital signal. The processor 330 may operate in one of a first operation mode for storing the electrocardiogram digital signal in the memory 360 and a second operation mode for transmitting the electrocardiogram digital signal to an external electronic device. The processor 330 may operate in the first operation mode or the second operation mode or may operate simultaneously in the first operation mode and the second operation mode.

In the second operation mode, the processor 330 may transmit, to the external electronic device, the electrocardiogram digital signal stored in the memory 360. The external electronic device may be implemented as a smartphone, a table personal computer (PC), a mobile phone, a video phone, an e-book reader, a desktop PC, a laptop PC, a netbook computer, a workstation, a server, a personal digital assistant (PDA), a portable multimedia player (PMP), an MP3 player, a mobile medical device, a camera, a wearable device, or the like, including one or more processors. The external electronic device includes a memory and may be in the form of a storage medium including a processor for controlling the memory. The external electronic device may include a communication interface for communicating with the electrocardiogram measuring device 300 or may be connected to an additional communication interface to operate.

In the first operation mode, the processor 330 may store, in the memory, an electrocardiogram digital signal merged with a user input. The processor 330 may receive the user input from an input unit (not shown), which is electrically connected, or a user terminal, which is connected through a communication network. The processor 330 may convert an electrocardiogram signal by using the received user input and generation time information of the user input.

In the first operation mode, the processor 330 may merge the electrocardiogram digital signal with the user input and store, in the memory 360, the electrocardiogram digital signal merged with the user input by using the generation time information of the user input.

In the second operation mode, the processor 330 may transmit, to the external electronic device, the electrocardiogram digital signal merged with the user input. The external electronic device may store the received electrocardiogram digital signal in a memory or may output the received electrocardiogram digital signal through an output unit.

The processor 330 may automatically change an operation mode considering a communication state with the external electronic device. For example, when the communication state with the external electronic device is abnormal, the processor 330 may stop the second operation mode and change the second operation mode to the first operation mode to operate.

When the communication state is normal again, the operation mode is changed to the second operation mode again. After the operation mode is changed to the second operation mode, an electrocardiogram digital signal measured in real time may be transmitted to the external electronic device.

The processor 330 may further include a temperature sensor, a motion sensor, a proximity sensor, a sound sensor, or the like.

The processor 330 may generate an electrocardiogram digital signal merged with a tag corresponding to information acquired by analyzing the electrocardiogram digital signal. The processor 330 may operate in the first operation mode and/or the second operation mode for the electrocardiogram digital signal merged with the tag.

The information acquired by analyzing the electrocardiogram digital signal may be a heartrate, cardiac component information, the maximum magnitude value, time information of a cardiac feature point, waveform magnitude information of the cardiac feature point, or the like. The maximum magnitude value refers to the maximum value of the magnitude from among the signal magnitudes of the electrocardiogram digital signal.
